The
hydroxyaldehyde shown cyclizes to form a hemiacetal under acidic or
basic conditions. Use wedge-dot structures to draw the two
stereoisomers formed from the aldehyde when it cyclizes. Explain if
the relationship between the products is the product mixture
expected to be optically active or optically inactive.

Draw a mechanism for an esterification reaction between phthalic anhydride and ethylene glycol under acidic conditions. (I need help seeing how this reaction would occur with a molecule such as phthalic anhydride, thanks!)
Ethers can be formed under acidic or basic conditions. What are the limitation of forming an ether from an alcohol under acidic conditions? I. Asymmetrical ethers cannot be formed exclusively under acidic conditions II. Rearrangement in the carbon skeletal backbone is possible under acidic conditions, III. Ethers in which the carbon bound to oxygen is 3° are not possible. IV. Intramolecular cyclization reactions are not possible under acidic conditions.
Hemiacetal formation occurs under acidic, basic, and neutral conditions. Under what set of conditions will acetal formation not occur?
The hydroxyaldehyde shown cyclizes to form a hemiacetal under acidic or basic conditions. Use wedge- dot structures to draw the two stereoisomers formed from the aldehyde when it cyclizes.
